Comment:

From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.

MABAH-133	1934-02-15	-1.4317	66.5700	-3385	Monegasque Trawl	MABAH-133-1	Surface	Mn coating	Many	8.0 to 1.0 cm	Rock; gabbro	Hard bottom	About 40 small rock fragments were brought up in the Monegasque net. Varying in size from 8 cm to 1 cm. All the rocks have a black coating, but in the majority this skin is of negligible thickness. They are angular.	96626 E (1) to 96626 E (20)
MABAH-133	1934-02-15	-1.4317	66.5700	-3385	Monegasque Trawl	MABAH-133-2	Surface	Mn nodule	Several	4.0 cm	Core; gabbro	Hard bottom	Exceptionally, however, the form is rounded into a nodule. In this case the coating may attain to 0.5 cm (St. 133, 8). If such a specimen is sectioned, the interior is revealed to be rock surrounded by a peripheral black coating	96626 E (1) to 96626 E (20)
MABAH-166	1934-04-23	6.9167	67.1833	-4793	Monegasque Trawl	MABAH-166-1	Surface	Mn nodule	Many	6.0 to 1.0 cm	Core; palagonite	Red clay	125 kg of manganese nodules associated with red clay deposit. Shapes are very varied: hemispherical, mammiliated, tetrahedral, cylendrical to saucer like.	96626 F (1) to 96626 F (81)
